The machine is equipped with an efficient fan to cool the 
motor. Cooling air which is drawn in through the grille by the 
machines rear handle passes over the stator and rotor and 
out through the front of the motor housing.

In order for the machine to always be cooled sufficiently the 
cooling air openings must be kept clear and clean. Blow down 
the machine regularly with compressed air.

The machine can withstand taking in damp air and splashes 
during the cutting process. Clean water does not affect the 
machine’s function.

When cutting materials such as concrete or brick, which can 
contain salt, you must rinse the machine after the work is 
finished. The cleaning reduces the risk for accretions building 
up inside the engine, which can cause leakage current 
between electric components, which in turn can cause the 
ground fault circuit interrupter to turn off without intention.

•

Clean the machine daily by rinsing it with clean water after 
the work is finished.

•

Place the machine with the rear handle facing upwards. 
Rinse the air intakes at the rear handle with clean water. 
The water will run out through the front air outlets.

•

Connect the plug and run the engine dry for approx. 30 
sec in order to speed up the drying of the engine.

Check that the cord and extension cord are intact and in good 
condition. Never use the machine if the cord is damaged, 
hand it in to an authorized service workshop for repair.

Check the carbon brushes at least once a month. The carbon 
brushes should be replaced with new brushes if they are 
worn, cracked or in any other way deformed.

All carbon brushes must be replaced when the brushes are 
replaced.

•

Remove both inspection covers by loosening both screws.

•

Unscrew the cable holding the carbon brush. Now lift up 
the spring and then lift out the carbon brush from the 
brush retainer.

•

Clean the brush retainers with a dry brush.

•

Carefully blow away the dust.

•

Fit the new carbon brushes and, at the same time, check 
that they slide easily in the brush retainers.

•

Fold down the springs and tighten the cable.

•

New carbon brushes must be run in for approximately 40 
minutes while idling.
